I've got 2 bits of info saved - use whichever seems appropriate:
SECS Monitor Wiring
WHITE à ECU PIN 15 MAP SENSOR
YELLOW à ECU PIN 31 AIR CHARGE TEMPERATURE SENSOR
BLUE à ECU PIN 29 ENGINE COOLANT TEMPERATURE SENSOR
GREEN à ECU PIN 17 THROTTLE POSITION SENSOR
GREY* à ECU PIN 25 IGNITION SIGNAL FOR RPM READING
RED à ECU PIN 20 +12V SUPPLY
BLACK à ECU PIN 1 GROUND
*Grey is only for the revised model - older versions didn’t show the RPM
IF you still have the original SECS loom from the monitor to the ECU loom then this will apply...
CONNECTOR 1 PIN 1 - WHITE WIRE - MAP SENSOR - ECU PIN 15
CONNECTOR 1 PIN 2 - YELLOW WIRE - CHARGE AIR TEMPERATURE SENSOR - ECU PIN 31
CONNECTOR 1 PIN 3 - BLUE WIRE - COOLANT TEMPERATURE SENSOR - ECU PIN 29
CONNECTOR 1 PIN 4 - GREEN WIRE - THROTTLE POSITION SENSOR - ECU PIN 17
CONNECTOR 1 PIN 5 - GREY WIRE - ECU IGNITION SIGNAL INPUT - ECU PIN 25 (IF FITTED)
CONNECTOR 1 PIN 6 - NOT USED
CONNECTOR 1 PIN 7 - RED WIRE - 12 VOLT POSITIVE SUPPLY - ECU PIN 20
CONNECTOR 1 PIN 8 - BLACK WIRE - GROUND - ECU PIN 1
CONNECTOR 2 PIN 1 - BUTTON 1

Cool cheers was thinking the same will get a new one and see what happens!!
Just realised my dash clocks are out at mo which probably explains the charging fault!
What should the map sensor be reading on idle just out of interest?!

Yea I know Martie but it was fine before I took it off the road and the only thing different is the clocks are out which from memory happens if their not plugged in cos the warning light is an open circuit?!
If it's not that then obviously will start looking into the alternator wiring

Too many posts.. I need a life!!
I have this exact problem with my car. SECS shows low battery alarm and voltage drops to below 10V, but battery voltage measured with a multimeter is always over 13V (up to 13.8V) depending on what's switched on. SECS is soldered straight into the ECU plug. Car drives fine, even at night with lights etc on. Alternator was a new Lucas item about 2/3 years ago.
Can you shed any light on this issue?

If you look at other circuits (i.e. the cigarette lighter) you will notice it here as well.
If you look near the battery, you will see them, do NOT be tempted to simply replace them with cable though!

Last Time, Get Off PF FFS
I had the same and it ended up being the battery warning bulb not inplace properly and the volts went back up both at the battey terminals and the monitor and as mentioned had to rev to 3k for it to chargenthe battery before i found the bulb to be at fault.

It's reading better now at 12.5v but not had a proper chance to look at it and would prefer to see 13+ volts!
Will have a proper look at it soon when I have the energy lol, but all warnings have gone now voltage has improved and change the act sensor!
